远视与干眼症的相关分析

Relative Analysis between Hyperopia and Dry Eye Syndrome

目的：分析远视与发生干眼症的关系。方法：选取2007—05／2008—07张家口市第四医院门诊就诊的患者155例310眼，均排除眼部感染性疾病、免疫性疾病、屈光问质混浊、视网膜疾病及既往眼部手术史。年龄为16～60岁，行症状、泪膜破裂时间（breakuptime，BUT）、基础泪液分泌试验（schirmer I test，SIT）、下睑中央泪河高度、角膜曲率及屈光状态检查。结果：（1）远视的BUT明显缩短，与正视眼之间差异有统计学意义（P％0．01），高度、中度、低度远视之间BUT有统计学差异（P=0．013）；（2）远视的Sit缩短，与正视眼之间SIT差异无统计学意义（P=0．20），高度、中度、低度远视之间Sit差异无统计学意义（P=0．066）；（3）远视的角膜荧光素染色评分增加，与正视眼之间差异无统计学意义（P〉0．05）；（4）远视的下睑中央泪河高度减少，与正视眼之间差异无统计学意义（P〉O．05）。结论：远视可引起泪膜功能不稳定，导致干眼症的发生，主要表现BUT明显缩短，SIT降低。

Objective：To analyse the relationship between hyperopia and dry eye syndrome. Method：All of 155 cases（310 eyes,aged 16-60 years） who were excluded to diagnose as infectious diseases of eye,immunological disease of eye,opacity of refractive media,retinal diseases and previous surgical history of eye were examined in symptom,breakup time（BUT） ,schirmer I test（SIT） ,center lacrimalriver highness of lower eyelid,keratometer and refraction. Results： （1）The BUT of patients with hyperopia was obvious shortening, compared with emmetropia, there was a statistical difference（P〈0.01）. Between high,middli and low degree hyperopia, there was a statistical difference（P =0. 013）. （2）The SIT of patients with hyperopia was shortening, compared with emmetropia,there was no statistical difference（P=0. 20）. Between high,middli and low degree hyperopia, there was no statistical difference（P= 0. 066）. （3）Fluorescein staining scores of patients with hyperopia increased but there was no statistical difference（P 〉0.05） compared with emmetropia. （4）The center lacrimalriver highness of lower eyelid decreased but there was no statistical difference（P〉0.05） compared with emmetropia. Conclusion： Hyperopia can lead to the tear film function instability and then create dry eye syndrome. It main shows that the BuT is obvious shortening and the SIT is lower.
